2. Hundreds and higher orders

The lesson, step by step

1. Warm-up

   Ask quickly: 10 tens make how many? (100.) 4 tens and 3 units? (43.) What figure holds an empty place? (0.)

2. Hundreds

   Read the definition.

   Units of the third order are called hundreds; and the place they occupy is called the hundreds' place.

   Write 345 and point: 3 hundreds, 4 tens, 5 units.

3. Zeros that hold a place

   Write 305 and 350. Say: Both have a 3 and a 5, but they're different numbers. The 0 holds an empty place.

   Have your child say each one as hundreds, tens and units.

4. Write and read together

   Do the first items of "Numbers to be written" for Article 7 together:

   One hundred and thirty; one hundred and forty; one hundred and fifty.

   Then read a few from "Numbers to be read" aloud.

5. The big idea

   Read Article 8.

   Invariably, ten units of any order make a unit of the next higher order,

   Say10 units make a ten, 10 tens make a hundred, 10 hundreds make a thousand, and it keeps going the same way forever.

6. On their own

   Your child finishes both lists for Article 7: writes the first list in figures and reads the second aloud.

7. Wrap-up

   SayHow many tens are in 300? (30.) How many hundreds in 1000? (10.) What number is 1 more than 399? (400.)
